Greta and Gracie are sisters. Greta is chatty while Gracie is quiet. It's all fine until, one day, everything changes. It's almost Christmas, and the sisters decorate the tree, shop for presents, and go ice-skating on the pond. Greta, of course, always knows best.
Then on Christmas Eve, while Greta is sleeping, Gracie hears a funny noise. She creeps downstairs to investigate, and the next morning her very special revelation leaves chitty-chatty Greta lost for words!
